• at least partially releasing at least a portion of an attractant composition from a container, thereby attracting the insects to the site of release;
• Catch the attracted insects;

wherein the attractant composition comprises a compound having a specific structure. It further relates to the use of such an attractant composition and specific attractant compositions as such.

Wood is one of the most important, diverse and widespread building materials worldwide. Celluloses and lignins, which are used as organic material in derived products but are eaten by many organisms as food and thus degraded, are the main properties that determine positive properties.

In addition to fungi / yeasts, here are mainly arthropods (especially insects) to call, often as a community of species, the degradation in community (symbiosis) accomplish. Substantial economic damage thus results from these destructors or their interplay, which as higher organisms, depending on the type of diet, e.g. as phloeophag, xylophag, myzetophag or in combination as xylomyzetophag can be called.

The most important of these harmful organisms are termites (Isoptera), ants (Formicidae) and beetles (Coleoptera) among other groups with similar feeding behavior. Within the beetle occur v.a. Cerambycidae, Scolytinae, Curculionidae, Anobiidae or Lyctidae as wood pests in appearance.

Another group exemplified below are the beetle beetles (Lymexylidae) with about 50 species occurring worldwide. Their larvae, which live in the wood body of usually dead or felled trees, are associated with specific and unspecific fungi, yeasts and bacteria, and feed on their metabolic products or, optionally, on the woody material itself.

Of the world's only few species of Lymexylidae several have emerged as economically significant wood / Lagerholzschädlinge , to mention here are Melittomma sericeum in North America on chestnut, Protomelittomma insulare in the Seychelles on coconut palms, Atractocerus brevicornis in Central Africa inter alia at Teak, A. kresulerae in Australia at Eucalyptus and A. reversus in India at Frankincense ( Boswellia spec.). Of the 4 species detected in Europe, two are classified as wood pests.

Particularly interesting for the invention are xylophage or xylomycetophage arthropods whose life cycle includes association with microorganisms such as fungi / yeasts or bacteria. In particular, this applies to the families Scolytinae and Lymexylidae, and especially so-called Ambrosia species, especially species of the genus Elateroides (in the literature Hylecoetus is used synonymously), here especially the species Elateroides dermestoides, Elateroides flabellicornis, Elateroides formosanus, Elateroides orientalis and Elateroides lugubris within the family of Lymexylidae.

Elateroides dermestoides occurs everywhere in the area of occurrence as a significant woodpile pest on almost all local tree species (seventy-five percent of Germany's forest area is planted with tree species that can represent breeding material) on. Treatises on the damage and the control of the beetle can be found in all standard and textbooks of forestry entomology and are still today's treatment recommendations ("fastest possible removal of (coniferous) wood outside the forest (or in deciduous forest areas) during the flight time and onset of infestation ") hardly more advanced than the knowledge of the founders of forest protection in the early nineteenth century (" they are certainly met by cleanliness in the forest, namely, by clearing away the windfalls and clearing the old sticks ").

A short presentation of the biology and a comprehensive current overview of infestation conditions, infestation process and defense against infestation, is a 2005 study entitled "Investigations on the infestation conditions, infestation and the defense of the infestation of deciduous and coniferous wood by the sinner Beetle beetles ( Elateroides dermestoides Latr. [Coleoptera, Lymexylidae]) The Forest Research Institute Baden-Württemberg reports there on current damage events, provides an overview of the damage in the past and attempts to assess the suitability of various new possibilities of infestation ( The result of this investigation is the authorization of an insecticide as a plant protection product for the protection of lumber camps from Elateroides dermestoides and the approval for the treatment of packaging materials, which may be used for: is intended for export.

The damage that causes Lymexylidae are mainly the technical devaluation of the affected wood. High-quality woods (veneer, furniture, parquet, stave wood) must be free of boreholes and fungi (blue fungi), which are often caused and registered by insects. An infestation The beetle eliminates such uses and leads to significant discounts in sales proceeds.

A species-specific quantification of infestation is not made in the general impact and trading events. Due to the increasingly extensive management of the forests and the higher degree of mechanization, wood stocks lying on the ground rise in the form of sticks, chippings and crown material. This material is depending on the type of wood, assuming appropriate dimensions, at least in the first year for Elateroides dermestoides sometimes attractive until the third year after precipitation. It can be assumed that in this way the increasing temporal equalization and single-strain use of the target strength in combination with the weather patterns that develop as a result of possible global warming to generally higher temperatures and associated storm events will increase the populations of Elateroides dermestoides .

Another reinforcing factor is the increasing presence of dead wood left for the promotion of biodiversity in the forest stands, as well as increasing damage to living trees, which is known as "beech complex disease" among other things for Fagus sylvatica . Reasons for this are seen in increased nitrogen inputs or possibly changed climatic conditions. The future development of this phenomenon is open and may mean a further increase in damage.

The timely removal of the wood from the forest or its rapid dehydration are required for years as the only solution so far to avoid the infestation of the wood.

Due to the hidden habit of the larva in the wood body, attempts to control it with insecticides and pesticides have so far often been in vain. Successful killing of the larvae can only be achieved with chemical substances whose human toxicity or toxic effects on non-target organisms prohibit the use (see patents and patent applications DD 143721A5 ; DD 141831A5 ; DE 69717927T2 ; DE 69410042T2 ; DE 68902372T2 ; DE 3872634T2 ; DE 3485788T2 ; DE 2826893A1 ; DE 2029753A ; DE 1966823C3 ; DE1966823B2 ; DE 1966823A ; DE 1266479B ; DE 1266479A ).

Since a killing of the larvae in already infested wood so eliminated, the only remaining option is the new case, so the oviposition, to prevent. As a preventive measure, the treatment of endangered wood with pesticides is possible in principle. The Northwest German Forestry Research Institute (Forest Protection Info No. 8, 2007 ) states: "From the middle of July can be mainly on reclining oak and beech, but also on other types of wood such Spruce and Douglas fir, may be observed very large Bohrmehlhäufchen. It is most likely to be the Saurel Beetle Beetle ( Hylecoetus dermestoides ), which has already colonized these woods in mid-April. An infestation by ship beetle usually leads to complete devaluation. Preventive should have been acted before the beginning of the flight time (mid-April), a (successful!) Curative treatment is no longer possible at the present time. "

Plant protection products, whose penetration into the wood body is low, only work effectively when applied before the larvae drill into the wood. However, a so-called "preventive polterschutzspritzung" is only indicated in exceptional cases after so-called "good forest practice" and thus for legal reasons (Plant Protection Act § 2a). At present, only one active substance is approved for use against Elateroides dermestoides (lambda-cyhalothrin), but its use is subject to restrictions.

In forestry companies, which are subject to a certification for natural silviculture (eg FSC or PEFC), its use is sometimes completely prohibited. According to the above-mentioned approval of pesticides against Elateroides dermestoides, "preventive only a property protection of valuable wood at a known hazard" is allowed, but unaware of the local real flight time and the lack of knowledge about local population densities often can not take targeted and therefore ineffective. The determination of the risk takes place according to unsafe criteria.

The approval of the use of pesticides thus requires conditions whose (spatial, temporal, target-specific) compliance may only make possible or significantly specify an attractant.

An effective insecticide control is therefore only possible during the very short flight time. This is exceptionally short for Elateroides dermestoides in a few days to weeks compared to other species ( Erwin Graf, Pius Manser, "Contribution to the introduced black forest bark beetle Xylosandrus germanus. Biology and damage potential of logs stored in the forest in comparison to xyloterus lineatus and Hylecoetus dermestoides", Switzerland. Z. Forstwes. 151 (2000) 8: 271-281 ) and dependent on locally varying weather and climatic conditions.

In order to determine the local flight time, a monitoring system is required, which until now was not available due to a lack of suitable attractants.

In the forestry practice Elateroides often syntopic (at the same time in the same place) with other wood pests of the family of Scolytinae (bark beetle) before. Here especially Xyloterus lineatus, X. domesticus, X signatus and others whose damage pattern only with appropriate Expertise can be reliably differentiated. This is a key reason for only uncertain knowledge about the actual extent and spread of damage in European forestry by Elateroides spec. caused. Often damages of the above mentioned species are summarized for lack of distinction to damages by "wood breeders". This represents a significant problem both for the authorized use of plant protection products and for a species-specific assessment of the damage, which can be solved by an efficient, art-selective attractant.

In all periods of historical forest protection, experiments were carried out with the pesticides and insecticides available against Elateroides dermestoides . In other European countries and Eastern Europe, such experiments were carried out, for example, with pyrethroids, chlorinated hydrocarbons and organophosphates.

In addition to the possibility to treat already infested wood with insecticides to stop the infestation, it is possible to protect the infestation with a so-called curative treatment before drilling in the larvae. Problems here are above all the temporally synchronous employment to the course of flight of Elateroides dermestoides, which is locally often not exactly known in the absence of an effective catching system. In the past, the possibilities of using wet storage, mineral protective covers, and foil packaging as protection against insect infestation were also examined. Although successful in use against other wood insects, none of the three studied procedures could provide safe protection against elateroides dermestoides infestation. Even with the use of pesticides, individual drillings were observed. The experiments can be considered unsuccessful.

The knowledge about attractants is bezgl. Elateroides dermestoides low ( Brattli et al., J. Appl. Ent. 122, 345-352 (1998 )). One substance that has been shown to have an attractant effect on many xylophagous insect species, and whose luring effect has also been known on Elateroides dermestoides since the 1980s, is ethanol. However, the attracting effect, as has been shown in numerous studies, is low compared with the effect on other insect species. It can thus hardly meet infection prognoses or general statements on the occurrence of Elateroides dermestoides .

In the literature, general forest protection measures to avoid an infestation are repeatedly cited: "debarking of the rootstocks before the precipitation", "immediate debarking of the trunks", "shortest duration of storage in the forest", "removal of the wood at the latest before the start of the flight of the insects" , "Just-in-time precipitation", "storage of wood outside the forest", "seasonally late felling dates", "storage in dry, sunny and wind-exposed locations", "clearing and removal or incineration of rhizomes".

However, forestry practice has for decades demonstrated that farm restrictions often prevent these measures: current changes in the wood market, i. Economic pressure and high costs are demanding increasingly streamlined timber harvesting measures. In addition, there are extended storage times in the forest due to a drastic increase in the woodworking businesses and associated longer access routes and in relation to lower storage capacities in operation with the consequence of storage in the casualty-exposed forest camp. Extensive management leads to the accumulation of storage, residual and deadwood on the forest road and in the areas that are the ideal breeding and habitat for wood-populating insects. Increases in the number of forest enterprises with decreasing personnel density are clearly counteracting the forest protection measures.

• zumindest teilweises Freisetzen zumindest eines Teils einer Lockstoffzusammensetzung aus einem Behälter, wodurch die Insekten zum Ort der Freisetzung angelockt werden;
• Fangen der angelockten Insekten;
  wobei die Lockstoffzusammensetzung eine Verbindung gemäß der folgenden allgemeinen Formel umfasst:
  
  wobei X und Y gemeinsam für:
  
  stehen und wobei R₁, R₂, R₃, R₄, R₅, R₆, R₇, R₈ und R₉ unabhängig voneinander für Wasserstoff, verzweigtes oder unverzweigtes Alkyl, verzweigtes oder unverzweigtes Alkenyl, oder substituiertes oder unsubstituiertes Aryl stehen.

According to the invention, the object is achieved by a method for attracting cambiophage, xylophage and / or mycetophage insects, comprising the steps:

• at least partially releasing at least a portion of an attractant composition from a container, thereby attracting the insects to the site of release;
• Catch the attracted insects;
  wherein the attractant composition comprises a compound according to the following general formula:
  
  where X and Y are common to:
  
  and wherein R ₁ , R ₂ , R ₃ , R ₄ , R ₅ , R ₆ , R ₇ , R ₈ and R _{9 are} independently hydrogen, branched or unbranched alkyl, branched or unbranched alkenyl, or substituted or unsubstituted aryl ,

The release of the attractant composition can be done inter alia by means of a dispenser attached to an insect trap. It is also possible, for example, for the attractant composition to be released on a pile of peat, gassed or unpoisoned.

The catching of the insects can be done, for example, in a live trap, in an adhesive trap or in a poison trap.

Surprisingly, it has been found that the compounds of the above general formula have a luring effect. Target insects may be cambiophage, xylophage and / or mycetophage arthropods such as termites (Isoptera), ants (Formicidae) or beetles (Coleoptera), in particular Lymexylidae.

In this way, for example, the following plants can be protected: Fagaceae, Rosaceae, Juglandaceae, Betulaceae, Sapindaceae, Oleaceae, Pinaceae, Magnoliaceae, Ulmaceae (Ulmus), Moraceae (Mora, Ficus), Arecaceae (Stevensonia, Nephrosperma, Deckenia, Roscheria), Myrtaceae (Eucalyptus), Burseraceae (Boswellia), Anacardiaceae (Lannea, Mangifera, Anacardium, Buchanania, Semecarpus), Fabaceae (Prioria, Albizia, Baikiaea, Mildbraediodendron) Meliaceae (Khaya, Ekebergia, Swietenia), Malvaceae (Bombax, Triplochiton), Combretaceae (Limba, Terminalia), Lamiaceae (Tectona), Euphorbiaceae (Ricinodendron, Hevea), Dipterocarpaceae (Dipterocarpus, Dryobalanops), Apocynaceae (Funtumia),

Specifically, these may be the following beetles: Triplax russica, Rhizophagus bipustulatus, Cantharis fusca, Ampedus sanguineus, Adalia decempunctata, Byrrhus pilula, Anatis ocellata, Mesosa nebulosa, Exochomus quadripustulatus, Tritoma bipustulata, Hister unicolor, Sinodendron cylindricum, Stenostola ferrea, Stenostola dubia, Coroebus rubi, Strangalia maculata, Clytus arietis, Necrophorus vespilloides, Melondrya caraboides, Bolithophagus reticulatus, Mycetophagus quadripustulatus, Mycetophagus atomarius, Rhagium bifasciatum, Hypophloeus unicolor, Rhizophagus dispar, Silvanus unidentatus, Litargus connexus, Pyrrhidium sanguineum , Pyrochroa coccinea, Aseleva sanguinicollis, Systenocerus caraboides, Malachius bipustulatus, Mycethophagus atomarius, Nosodendron fasciculare, in particular Elateroides dermestoides, Elateroides flabellicornis, Elateroides lugubris and Lymexylon navale.

Effective insecticide control is only possible during the very short flight time of the insects. This is extremely short in a few days to weeks compared to other species, in own investigations 85% of the total catch of E. dermestoides was reached within 3 fishing days, whereas this threshold in syntopic species (Scolytinae) only after one and a half despite using species-specific aggregation pheromones reached up to three months ( Erwin Graf, Pius Manser, "Contribution to the introductory black forest bark beetle Xylosandrus germanus." Biology and damage potential of logs stored in the forest in comparison to xyloterus lineatus and Hylecoetus dermestoides ", Switzerland. Z. Forstwes. 151 (2000) 8: 271-281 )).

Furthermore, the flight time and thus the effectiveness of a trap system is highly dependent on locally varying weather and microclimate conditions. In order to determine the local flight time, a monitoring system is required, which until now was not available due to a lack of suitable attractants. The solution according to the invention first makes it possible to aggregate beetles effectively and to use insecticides specifically and thus spatially limited (for example, removed from special protection biotopes according to §29 Federal Nature Conservation Act).

The following table summarizes the previous practice and its problems as well as the advantages of the solution according to the invention, in particular with regard to shipyard beetles: Previous practice / problem Advantages of invention Population densities (= hazard potential) generally unknown effective monitoring traps with attractant possible spatial distribution of the beetles unknown Localization of unexploded timber wood sites with low population density through monitoring traps, monitoring of the timber storage possible Efficacy of PSM / insecticides limited in time, no repeat treatment allowed optimal and effective (short beetle flight time) Termination of PSM deployment through monitoring traps Defense with PSM only curative without push-pull possibilities Pull compartment through local mass catching with traps - efficient use of PSM possible no fishing lures available (low attraction) effective fishing sticks with PSM & attractant combination Hard-to-distinguish damage from timber bark beetles Xyloterus spec. now available for both species species-specific attractants (combination preparations are possible) Certified Forest Services (FSC / PEFC) are subject to PSM restrictions Push-pull method with Lock / Distractor is a biological V. & enhances spatial limitation of PSM use - preferred by certifiers or strictly allowed. Avoidance of infestation only through seasonal early removal and processing Extension of storage times possible through fall protection

For carrying out the process according to the invention, solvent-based evaporation vessels (optionally capillary systems) or commercially available dispensers (eg bag systems, bottle membrane evaporation, polymer embedding, capillary systems of, for example, the companies Pheronova AG Glattbrugg, Switzerland; Wilhelm Biologischer) are advantageously used for dispensing the substances and mixtures Pflanzenschutz Sachsenheim "Langlock Dispenser", Neudorff GmbH KG, Emmerthal).

The method according to the invention can be used, for example, as a component of push / pull strategies, monitoring and mass capture.

Push / pull strategies are used to manipulate the behavior of pest insects and their natural predators by incorporating and intertwining stimuli that, on the one hand, make the material to be protected (tree, lumber, raw wood, lumber) unattractive or unusable (Push), at the same time on the other side the pest insects attract to an attractive source (pull), from where the animals are continuously removed (eg trap). The "push" or "pull" components are generally non-toxic. In particular, push-pull strategies act by maximizing the efficiency of behavioral stimulants by additive or synergistic use thereof.

Stimulants used as "push" components can be removed or applied with commercially available manual, motor-driven or machine-operated sprayers as used in any forestry or agricultural operation. Thus, depending on the application or hazard, a single trunk or whole wood polter or wood storage can be treated.

In addition to a general commission for environmental monitoring (§15 BnatSchG), the temporal and spatial knowledge of the occurrence of a forest conservation is within the bounds of the principles of integrated forest protection within the regulated forestry, and in accordance with the provisions of the nature conservation and plant protection laws for extensively or unmanaged forests Insect pest of primary importance. The attractants proposed here serve to fulfill this fundamental task. The knowledge gained from this is used for the development, improvement, but above all for the targeted application of action strategies in dealing with pest insects. Existing strategies are significantly increased in their efficiency, or even made possible.

Regardless of the o.g. Applications, the inventive method for increasing the effectiveness of an insecticide or corresponding, even biological control method can be used. By influencing a predictable distribution of a pest, the efficiency of all population-reducing methods is increased. For this purpose, all already known fishing methods, such as those used for example for barking beetle control, or for controlling ants and termites can be used. For the flying stages of the target organisms mainly fly traps, in the close orientation of the same, or the flightless animals and stadiums can be used adapted and already known trapping systems for running organisms.

In a further embodiment of the method according to the invention, the attractant composition further comprises formulation auxiliaries which are selected from the group comprising surfactants, fillers, creep agents, thickeners and / or stabilizers.

The attractant compositions can be formulated in various ways, depending on which biological and / or chemical-physical parameters are given. Possible formulation options are, for example, wettable powders (WP), water-soluble powders (SP), water-soluble concentrates, emulsifiable concentrates (EC), emulsions (EW), such as oil-in-water and water-in-oil emulsions, sprayable solutions, suspension concentrates ( SC), oil- or water-based dispersions, oil-miscible solutions, capsule suspensions (CS), dusts (DP), granules (GR) in the form of micro, spray, elevator and adsorption granules, water-dispersible granules (WG), water-soluble granules (SG) , ULV formulations, microcapsules and waxes.

These individual formulation types are known in principle and are described, for example, in: Winnacker-Kuchler, "Chemical Technology", Volume 7, C. Hanser Verlag Munich, 4th ed. 1986 . Wade van Valkenburg, "Pesticide Formulations", Marcel Dekker, NY, 1973 . K. Martens, "Spray Drying" Handbook, 3rd ed. 1979, G. Goodwin Ltd. Lond on.

The formulation auxiliaries, such as inert materials, surfactants, solvents and other additives are likewise known and are described, for example, in: Watkins, "Handbook of Insecticide Dust Diluents and Carriers," 2nd ed., Darland Books, Caldwell NJ ., Hv Olphen, "Introduction to Clay Colloid Chemistry", 2nd Ed., J. Wiley & Sons, NY ., C. Marsden, "Solvent Guide", 2nd Ed., Interscience, NY 1963 . McCutcheon's "Detergents and Emulsifiers Annual", MC Publ. Corp., Ridgewood NJ ., Sisley and Wood, "Encyclopedia of Surface Active Agents", Chem. Publ. Co. Inc., NY 1964 . Schönfeldt, "Grenzflächenaktive Äthylenoxidaddukte", Wiss. Publishing company, Stuttgart 1976 . Winnacker-Kuchler, "Chemical Technology", Volume 7, C. Hanser Verlag Munich, 4th ed. 1986 ,

Injectable powders are preparations which are uniformly dispersible in water and, in addition to the attractant mixture, contain ionic and / or nonionic surfactants (wetting agents, dispersants), for example polyoxyethylated alkylphenols, polyoxethylated fatty alcohols, polyoxethylated fatty amines, fatty alcohol polyglycol ether sulfates, alkanesulfonates, alkylbenzenesulfonates, lignosulfonic acid sodium, 2,2'-dinaphthylmethane-6,6'-disulfonic acid sodium, dibutylnaphthalenesulfonic acid sodium or oleoylmethyltaurine acid. For the preparation of the wettable powders, the attractants are finely ground, for example, in conventional equipment such as hammer mills, blower mills and air jet mills and mixed simultaneously or subsequently with the formulation auxiliaries.

Emulsifiable concentrates are prepared by dissolving the attractant in an organic solvent, e.g. Butanol, cyclohexanone, dimethylformamide, xylene, diethyl ether, methyl tert-butyl ether or higher-boiling aromatics or hydrocarbons or mixtures of organic solvents with the addition of one or more surfactants of ionic and / or nonionic type (emulsifiers). Examples of emulsifiers which can be used are: alkylarylsulfonic acid calcium salts such as calcium dodecylbenzenesulfonate or nonionic emulsifiers such as fatty acid polyglycol esters, alkylaryl polyglycol ethers, fatty alcohol polyglycol ethers, propylene oxide-ethylene oxide condensation products, alkyl polyethers, sorbitan esters such as e.g. Sorbitan fatty acid esters or polyoxethylenesorbitan esters such as e.g. Polyoxyethylene. Dusts are obtained by milling the active ingredient with finely divided solids, e.g. Talc, natural clays such as kaolin, bentonite and pyrophyllite, or diatomaceous earth.

Suspension concentrates may be water or oil based. They can be prepared, for example, by wet grinding using commercially available bead mills and, if appropriate, addition of surfactants, as described, for example, in US Pat. are already listed above for the other formulation types. Emulsions, e.g. Oil-in-water emulsions (EW) can be prepared, for example, by means of stirrers, colloid mills and / or static mixers using aqueous organic solvents and optionally surfactants, as described, for example, in US Pat. listed above for the other formulation types.

Granules may be prepared either by spraying the attractant onto adsorptive, granulated inert material or by applying drug concentrates by means of adhesives, e.g. Polyvinyl alcohol, polyacrylic acid sodium or mineral oils, on the surface of carriers such as sand, kaolinites or granulated inert material.

Water-dispersible granules are generally prepared by the usual methods such as spray drying, fluidized bed granulation, plate granulation, mixing with high-speed mixers and extrusion without solid inert material.

For the production of plate, fluidized bed, extruder and spray granules, see, for example Method in "Spray-Drying Handbook" 3rd ed. 1979, G. Goodwin Ltd., London on, JE Browning, "Agglomeration", Chemical and Engineering 1967, pages 147 ff , " Perry's Chemical Engineer's Handbook, 5th Ed., McGraw-Hill, New York 1973, pp. 8-57 ,

It is possible to use known stabilizers, such as emulsifiers, antioxidants, phosphates and acid regulators, for the scavenging of reactive oxygen (for example vitamin E, tocopherols, BHT (butylhydroxytoluene), the buffering of the pH (for example ascorbic acid, citric acid, sodium citrate, tri- or Polyphosphates) or the light stability esp. The UV protection (hindered amine light stabilizers (HALS), hydroxybenzophenones, cinnamate esters and oxanilides) serve.

For further details on the formulation of crop protection products, as they can be applied analogously in the context of the present invention, see, for example GC Klingman, "Weed Control as a Science," John Wiley and Sons, Inc., New York, 1961, pp. 81-96 and JD Freyer, SA Evans, "Weed Control Handbook", 5th ed., Blackwell Scientific Publications, Oxford, 1968, pp. 101-103 ,

In a further embodiment of the method according to the invention, the insects attracted by the attractant composition are selected from the family of beetle beetles (Lymexylidae) . In particular, this may be the Sägehörnigen ship beetle, Elateroides dermestoides act.

In a further embodiment of the method according to the invention, the catching of the attracted insects takes place by means of a catching device which is selected from the group of the catching wood and the pile of catching wood, impact traps, glue traps and / or funnel traps.

In one embodiment of the attractant composition according to the invention this further comprises an insecticide.

Finally, the present invention also relates to an insect trap system comprising an attractant composition according to the invention. Suitable types of cases are, for example, impact traps, glue traps and / or funnel traps. An insect trap system is to be understood as meaning at least the trap provided with the attractant composition. This may be done, for example, by direct application or by a separate attractant container / dispenser / etc., Attached to or near the trap.

The present invention will be further explained with reference to the following application suggestions, but without being limited thereto.

Scented bait trap: In one variant, the trap has a surface, preferably a baffle, which is brown, black or green. In a further variant, the trap has a surface, preferably a baffle, which is transparent. In a further variant, the attractant container or dispenser is attached to the surface, preferably in the lower third of the case length. In a further variant, the trap is constructed such that the air space above the attractant container (s) or dispenser (s) is supplied to the catching container or the attractant is in the catching container. In another variant, the trap is located at a position of 0.5 to 2.0 meters above the surface at the location where the trap is deployed. The manner in which the trap is to be set up is known to the person skilled in the art.

Application suggestion 1: Monitoring for time of flight monitoring

For the monitoring and determination of local flight activities (monitoring) single or multiple traps can be set up in blocks of up to five. Single traps or blocks should have one Minimum distance of 100 meters. Traps within the blocks should not fall below a minimum distance of 20 meters. The traps are suspended free-rotating on wooden posts or metal gantries 0.5 to 2.0 meters above the ground or fixed with the baffle in the lee of the prevailing wind direction. The traps should be placed inside the holdings and should not exceed a distance of 50 meters from the edge of the forest. The distance to suitable, untreated wood should be at least 100 meters. The setting up of the traps and application of the attractants should be completed in the spring before the first occurrence of maximum daytime temperatures of 20 ° C, at the latest before the first week of April (depending on the altitude). The monitoring intervals should not be greater than one week between 15 April and 15 June (200 m asl, correspondingly extended for low mountain and mountain regions). For curative treatment of endangered wood with pesticides, treatment should be given no more than two weeks after the appearance of the first individual and, depending on the lifetime of the active substance, not later than four weeks.

Suggested application 2: Monitoring for the identification of safe wood storage bins

For the spatial monitoring and determination of safe wood storage areas with a low risk of infestation, one or more traps can be set up in blocks. Planned timber storage bins should be stocked with at least three traps at least 10 meters apart, one year before logging. At intervals of 30 to 50 meters and 100 meters, four traps should be placed in a cross position in all directions, regardless of the type of beetle and tree species - in forest edge camps also in the field. The traps are suspended free-rotating on wooden posts or metal gantries 0.5 to 2.0 meters above the ground or fixed with the baffle in the lee of the prevailing wind direction. The distance to suitable, untreated wood should be at least 100 meters. Within a radius of at least 100 meters around the selected storage area and the traps, suitable breeding material should be removed. The setting up of the traps and application of the attractants should be completed in the spring before the first occurrence of maximum daytime temperatures of 20 ° C, at the latest before the first week of April. The monitoring intervals should not be greater than one week between April 15 and June 15 (corresponding to longer at altitude). The fishing activity can be set at the end of June (altitude s.o.).

Proposal 3: Push / Pull for the protection of wood storage, integration with population-reducing methods

• Push-Komponenten werden im günstigsten Fall direkt auf zu schützendes Material aufgebracht. Bei der Verwendung von Dispensern werden in unmittelbarer Nähe zu dem zu schützenden Material mehr als 5 Dispenser in einem Abstand von höchstens 10 Metern installiert. Pull-Komponenten sollten im Abstand von 50-150 Metern zu dem zu schützenden Material bevorzugt in Blöcken von mindestens drei Fallen mit einem Abstand von mindestens 20 Metern installiert werden und können um dieses herum kreisförmig angeordnet sein. Sie sind vor allem im Lee der Hauptwindrichtung zu installieren. Es sollten mindestens drei Blöcke installiert werden. Brutfähiges Material ist im Abstand von 50 Metern um das zu schützende Material zu entfernen. Mehrere zu schützende Holzlager sollten bei einem Abstand von unter 300 Metern durch Repellent-Dispenser verbunden werden, ist der Abstand größer sollte je ein eigenes Push-Pull-Arrangement installiert werden.

To establish a push / pull system for controlling phloeophobic, xylophager or xylomyzetophager arthropods are the attractive substances and mixtures of substances according to the invention used. These represent Allomone, Kairomone or Synomone dar. They can be applied both directly by means of trap systems, but also to increase the attractiveness of so-called catch trees. Furthermore, pheromones can be combined with substances or mixtures of substances according to the invention. The substances and mixtures according to the invention can be supplemented by so-called non-host volatile (NHV), these are well known to the expert. They can also be dispensed with dispensers as used in the traps presented. Other useful dispensing systems such as glass capillaries or polymer based permeation systems are well known to those skilled in the art. The spatial arrangement can be done as follows:

• In the best case, push components are applied directly to material to be protected. When dispensers are used, more than 5 dispensers are installed at a distance of not more than 10 meters in the immediate vicinity of the material to be protected. Pull components should be installed at a distance of 50-150 meters from the material to be protected, preferably in blocks of at least three traps spaced at least 20 meters apart, and may be circular around it. They are mainly to be installed in the lee of the main wind direction. At least three blocks should be installed. Brooding material should be removed at intervals of 50 meters around the material to be protected. Several wood storage areas to be protected should be connected at a distance of less than 300 meters by means of a repellent dispenser. If the distance is greater then a separate push-pull arrangement should be installed.

Examples Behavioral experiments with attractant traps in the forest:

The behavioral tests described below were carried out in the periods 02.05.-30.06.2004, 06.05.-20.06.2005, 09.05.-22.06.2006 and 24.04.-31.05.2007 in a beech population north of Göttingen (Germany).

Cross window traps made of dark brown coated multiplex plywood (5 mm), previously used to catch bark beetles, 60 cm long and 25 cm in diameter, ending in a 25 cm diameter funnel were used black plastic lid (30 cm diameter) were protected against rain. At the bottom of the funnel opening (2.3 cm) was a 500 ml polyethylene catch bottle with metal gauze bottom for drip. Twenty centimeters above the hopper edge, at one-third the length of the baffle, was attached a polyethylene attractant bottle (100 ml) whose round orifice was 2.4 cm. A similar trap as a commercially available impact trap is e.g. available as "WitaPrall" from the company Witasek. For the experiments, seven traps were set up in five blocks in a beech tree. The traps had a minimum distance of 30 m, the blocks of 150 m. The traps were suspended from a metal boom at a height of 1.6 m (upper edge of traps).

The attractant formulation was dissolved in ethanol in an amount of 10 ml filled in the attracting bottle, and renewed every two days. Insects were caught live and removed from the fishing area every two days. In laboratory experiments, the evaporation rates of Neudorff-Dispensem were compared with the polyethylene attractant bottles used. Those may as well as e.g. Langlock dispensers of the company Wilhelm Biologischer Pflanzenschutz are used to achieve the effective rates of release. Likewise, with these sufficient evaporation rates can be provided over the entire flight period of 2 months with one to two fillings. For the evaluation of the individual experiments, daily catch totals relative to the total catch total of all (min.) 15 days were cumulatively displayed as an individual-time curve for the phenological monitoring.

FIG. 1 shows cumulative, relative individual time curves of the Elateroides dermestoides depicted for four fishing years, corresponding to the four subsequent examples (2004: diamond; 2005: square; 2006: triangle; 2007: cross) - ordinate: percent of the total; Abscissa: Monthly decimal.

For each experiment, a trap set of 35 traps was used at least the length of a total trapping period. After an experiment, the attractant occupancy was re-randomized. For evaluation, the catch totals of five traps per decoction formulation were formed and displayed over the entire flight time.
